A rhodium-catalyzed silylative cyclization of alkynes and 1,6-diynes with hexamethyldisilane is described. These reactions enable the synthesis of densely substituted silole derivatives through the use of a rhodium(I)-norborna-2,5-diene complex as a catalyst.
A series of inexpensive, easily tunable, and highly reducing organic photocatalysts (PCs) that exhibit strong absorption in the visible region are described. Time-dependent density functional theory calculations were applied to corroborate the experimental observations and explain the relationship between the structure and property. The photocatalytic efficiency of these PCs was demonstrated by catalyzing
